Have enough stock left to make a few more shock tower reinforcement kits if anyone is interested. Sadly, will be raising prices a bit after the next steel order due the rising costs of steel. Have 2 versions available, 67-70 & the new 65-66 kit. All pieces are available separately if you don’t want the full kit. If anyone is interested, shoot me a note & I can email/ text pics. Haven’t figured out a way to post pics here yet. 

67-70 kits (10 piece) $175 shipped in the states
65-66 kit (14 piece) $300 shipped in the states. 

also have no problem doing some good old horse trading for parts. Have a 65 fastback in “parts hunting” stage. Also have a 69 fastback I need a few things for, but almost complete.

Tinkered around today with the right side & made some positive progress. Addressed the issues on the axle where the studs had pushed up the edges of the holes. Dressed everything down with a file, took the old rotor from the left side that didn’t have the stud issues & lightly hit the backside of the lug holes with a 45 degree tapered reamer. Also noticed the aluminum rotor centering rings had a very sharp edge On the inside where it seats on the axle. Axle wasn’t machined to a precise edge where they meet so chucked the ring up in the lather and put a light 45 degree cut to that sharp 90 inside edge. Put the rotor on, torqued it down & first reading has the runout down to .004 at the rotor. Won’t mess with it any further until I get the new rotors in. If there is no improvement with the new rotor, one of the .003 runout correction shims would bring it in to .001. Don’t think I could ask for any better on that side...

Found it back around 07 looking at brake upgrades etc. after picking up my first old mustang in 20 yrs.

Nice! I’ve made much of my stuff too. Made all my hydraulic clutch brackets & crossmember for the T5 swap. I also make the shock tower reinforcement kits. Just developed a new kit for 65-66.

I’m pretty sure they came from MS, but could have been Ultrastang. Bought the car in 07 & started picking up parts soon after, so has been a good bit of time. 

will double check those calipers/brackets, but think it’s more of a runout issue. Did a little more monkeying around today & found that no matter how I clock the rotor on the axle, the high spot always stays in the same spot on the axle, doesn’t move with the rotor. Guess I’m going to have to start with the axles & work my way out.

Thanks for the replies! There are no residuals in the system. Everything was built brand new with the exclusion of the pedal. Car is a base model 69 sportsroof with 94k original miles. Rear is the original 8” with an added Eaton posi 3.73 gears. Here’s a parts list of the brake system:

Reman booster
Approx 2000 V6 master cyl. 
Wilwood adjustable prop valve. Not a single in/out but the combo one with the distribution block
All new stainless lines & hoses. 
Front is 05 GT using MS conversion brackets & new takeoff calipers/ rotors/ pads purchased from Shelby
Rear MKVII was salvage yard purchase, used calipers for cores, new pads & turned the original rotors. Also used MS bracket kit to mount. 

Going to start by addressing the issues I found on the axle around the lug studs & do some testing, now that I have the high/low spots marked. Ordering new set of rotors today. Only $18 ea thru rock auto & have a guaranteed lateral runout of .004 or less. Will also check for centering of the calipers, but think it’s good based on wear patterns on pads. Once I get the runout issues somewhat under control Will test with parking brake cables disconnected to make sure those aren’t creating a drag. Should I also back off the bias a little on the prop valve and see what that does?

I’m going to apologize up front if I start to ramble, my brain is on overload right now. Finally managed to squeeze a little free time into the schedule to work on solving this 9 yr, nagging problem that hasn’t been right since day one. I have the MkVII rear disc setup that started making a noise on day one of the install back in 2012. Sounded like a runout issue where the pads squeek a bit each revolution when the pads hit the high spot on the rotor. Took the rotors off, had them turned & had a mechanic buddy copy the ford manual pages on correct caliper adjustment. Double checked everything & still had the noise. Could back the pads off just enough to erase the noise, but then would lose parking brake functionality. A week later, before I could fiddle with it more, my father was killed & it just got shoved to the back of the to do list. Other than moving the car around, in & out of the shop etc, it didn’t get driven. In 2017 I moved & other than a couple trips to the main road & back, about 2 mi, it has sat covered up until today. Here’s what I have discovered & looking for advice on which direction to go to fix. 
1) took off wheels, disconnected driveshaft & was still very hard to turn until both calipers were removed.
2) spun rotors & marked the high spots where pads scraped on front & back. 

3) rigged up “redneck” dial indicator & Checked runout on rotors. Came up with roughly .030 between high & low areas. 
4) removed rotors & checked runout on axle flanges. One side was at .005, other pretty much 0. I did notice some other problems with the axles. Axles have long studs installed & noticed on a couple of the studs, the edges of the holes have bulges that interfere with the rotor. Also a couple other studs are long enough on the splined area to have splines sticking through & upon inspection, the lug nuts more or less press the rotor on when wheels are mounted & tightened. 
5) the axle that has a .005 runout when clocked with the high spot at 1

Board footera
